lymphomas of the gall bladder and extrahepatic bile ducts
Lymphomas of the gall bladder and extrahepatic bile ducts are exceedingly rare.
The most common primary lymphoma types were:
diffuse large B-cell lymphoma
extranodal marginal zone lymphoma
B-lymphoblastic lymphoma
follicular lymphoma.
Some cases have features of lymphomatous polyposis with follicular lymphoma or mantle cell lymphoma, with disease limited to the mantle zones, so-called in situ mantle cell lymphoma.
Other rare lymphoma subtypes in this site can be the extracavitary variant of primary effusion lymphoma and plasmablastic lymphoma.
Patients with diffuse large B-cell lymphoma and extranodal marginal zone lymphoma are older (mean age 75.8 y) than those with other subtypes (mean age 47 y) and more likely to have gallstones (60% vs. 12.5%).
Primary lymphomas of the gall bladder and extrahepatic bile ducts show a broad spectrum of disease types, but in many respects mirror the spectrum of primary lymphomas of the gastrointestinal tract.
